Call eth_chainId before using a wallet or client connection to Tavchain Testnet. Its numeric EVM chain ID is 771002.

Request

eth_chainId takes an empty parameter array.

set -e
curl --fail-with-body --max-time 10 \
  https://api.testnet.tavchain.safeney.com/ \
  -H 'Content-Type: application/json' \
  --data '{"jsonrpc":"2.0","id":1,"method":"eth_chainId","params":[]}'

Result

Expect result: "0xbc3ba", the hexadecimal representation of 771002. Native nodes use tavchaintestnet_771002-1; that string is not the wallet chain ID. A matching chain ID helps detect a wrongly selected endpoint. It does not independently authenticate the server.

Check progress

Use eth_blockNumber with an empty parameter array to read the current EVM head as a hexadecimal quantity. For a local node, inspect native sync status and peers using Monitor a node. Network settings · Response formats
